This note describes the process to update a Canadian historical snow survey dataset to 2016 and the production of a 0.1° gridded version for research applications. The Canadian Ice Thickness Program has two data collections that users can access anytime online: Ice Thickness Program Collection, 1947 to 2002 [XLS;4.1 MB] | Metadata; Ice Thickness Program Collection, Fall 2002 to 2020 [XLS; 182 KB]; The ‘Original Ice Thickness Program Collection’ contains ice thickness and snow depth measurements for 195 sites. Analyses. Hundreds of weather stations, ships, and aircraft across Canada, the US, and the rest of the world report readings of temperature, pressure, wind, moisture and precipitation. This paper describes the development of a new snow load map for defining ground snow loads for building (roof) design in the state of Colorado. Wind Load Calculators — Low rise buildings. Primary Structural Action (Fig. The newly proposed Colorado maps aim to ensure that structures designed across the state achieve the target safety index of 3 defined in ASCE 7. AccuWeather's Forecast map provides a 5-Day Precipitation Outlook, providing you with a clearer picutre of the movement of storms around the country. A second alternative to using the Zone map found below would be to use the chart found on the Zone map to determine the ground snow load for the specified geodetic elevation. Specified Snow Load (1) The specified load, S, due to snow and associated rain accumulation on a roof or any other building surface subject to snow accumulation shall be calculated from the formula, S = I s [S s (C b C w C s C a) + S r]. For an elevation of 212 metres, the ground snow load would be: 1.2 + (1.4/215) * (212-75) = 2.1 kilopascals . Understanding current conditions is the starting point, and the most critical part, of any weather forecast. Design shall accommodate all applicable load conditions (dead loads, live loads, wind loads, and seismic loads) and must conform to the current edition of the BC Building Code. The Ontario Building Code | Specified Snow Load 4.1.6.2. I-8) Wind load — Free standing plates, walls, and billboards (Fig. An estimated snow depth map National, US Snow Depth Map, covering much of Canada. where, I s = importance factor for snow load as provided in Table 4.1.6.2., In areas of the state outside of certified local government jurisdictions, the design snow load shall be based on the ground snow loads developed in "Snow Loads for Structural Design in Montana", authored by F.F. 7. The ground snow load map shown below was scanned from the ASCE 7-10 (Figure 7-1). The structural design and field review of non-structural elements, restraints, and anchorages shall be provided by a professional engineer registered in B.C. I-24) Earthquake Load Calculators. Structural Design of Non-Structural Components. Ground snow loads, p g , for the contiguous United States can generally be determined using this map. 1. In the 1985 edition of the National Building Code of Canada (NBCC) the intensity of the specified snow load at any location on a roof is obtained by multiplying the ground snow load for … Videon and J.P.
